ECMAScript compatibility shims for legacy JavaScript engines

es5-shim.js monkey-patches a JavaScript context to contain all EcmaScript 5 methods that can be faithfully emulated with a legacy JavaScript engine.

es5-sham.js monkey-patches other ES5 methods as closely as possible. For these methods, as closely as possible to ES5 is not very close. Many of these shams are intended only to allow code to be written to ES5 without causing run-time errors in older engines. In many cases, this means that these shams cause many ES5 methods to silently fail. Decide carefully whether this is what you want. Note: es5-sham.js requires es5-shim.js to be able to work properly.

json3.js monkey-patches the EcmaScript 5 JSON implimentation faithfully.

es6-shim.js provides compatibility shims so that legacy JavaScript engines behave as closely as possible to ECMAScript 6 (Harmony).

es7-shim.js provides compatibility shims so that legacy JavaScript engines behave as closely as possible to ECMAScript 7.

new RightAngledTriangle(x, y, h)

A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.

Example

var triangle = new RightAngledTriangle(3, 4, 5);
console.log(triangle.circumference()); // 12
console.log(triangle.area()); // 6

rightAngledTriangle.circumference() ⇒ number

The circumference of a right angled triangle is the sum of the three side lengths.

Circumference = x + y + h

Kind: instance method of RightAngledTriangle
Returns: number - The circumference unit distance measurement.
this: {RightAngledTriangle}
Access: public

rightAngledTriangle.area() ⇒ number

The area is given by the area formula for an arbitrary triangle.

Area = (1 / 2) * B * h

If the triangle is right angled, as in this case, the side y is the same as the height an y is the same as the base line.

Area = (1 / 2) * y * x

Kind: instance method of RightAngledTriangle
Returns: number - The area unit square measurement.

new Rectangle(x, y)

In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, since equiangular means that all of its angles are equal. It can also be defined as a parallelogram containing a right angle. A rectangle with four sides of equal length is a square. The term oblong is occasionally used to refer to a non-square rectangle.

Example

var rectangle = new Rectangle(3, 4, 5);
console.log(rectangle.circumference()); // 14
console.log(rectangle.area()); // 12

rectangle.circumference() ⇒ number

The circumference of a rectangle is the sum of the two side lengths then doubled.

Circumference = (x + y) * 2

Kind: instance method of Rectangle
Returns: number - The circumference unit distance measurement.
this: {Rectangle}
Access: public

rectangle.area() ⇒ number

To find the area of a rectangle, multiply the length by the width.

Area = x * y

Kind: instance method of Rectangle
Returns: number - The area unit square measurement.

new Circle(r)

A circle is a simple closed shape in Euclidean geometry. It is the set of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves so that its distance from a given point is constant. The distance between any of the points and the centre is called the radius.

Example

var circle = new Circle(3);
console.log(circle.circumference()); // 18.84
console.log(circle.area()); // 28.27

circle.circumference() ⇒ number

The circumference of a circle relates to one of the most important mathematical constants in all of mathematics.

Circumference = 2 * PI * r

Kind: instance method of Circle
Returns: number - The circumference unit distance measurement.
this: {Circle}
Access: public

circle.area() ⇒ number

To find the area of a circle.

Area = PI * (r^2)

Kind: instance method of Circle
Returns: number - The area unit square measurement.

new ShapesArea(...varArgs)

Total area of multiple shapes (not only triangles and rectangles but also other types of shapes that impliment #area).

Example

var shapesArea = new ShapesArea(triangle, rectangle, circle);
console.log(shapesArea.area()); // 46.27

shapesArea.area() ⇒ number
